PTFA260451E
Thermally-Enhanced High Power RF LDMOS FET
45 W, 2.62 – 2.68 GHz
Description
The PTFA260451E is a thermally-enhanced 45-watt, internally-
matched GOLDMOS ® FET intended for CDMA2000, Super3G (3GPP
TSG RAN), and WiMAX applications from 2.62 to 2.68 GHz. Thermally-
enhanced packaging provide the coolest operation available. Full
gold metallization ensures excellent device lifetime and reliability.
